Specification of Letters Patent.

Patented May 29, 1917.

Application filed August 19, 1914, Serial No. 857,612. Renewed November 2, 1916. Serial No. 129,230.

To all whom it may concern:

Be it known that we, SIMON E. SCHROEDER and- CHARLES W. Bran, citizens of the United States, residing at Minier, inthe county of 5 Tazewell and State of I1linois,have invent- 5 fed certain new and useful lrnprovementsin Gearing, of which the following 18 a specification.

1o rotary agitator class.

We are aware that rotary churns are known to the art, also we are aware that re ducing gear has been employed between the driving elernent and the churn, but in all churn structuresin this class that are now being marketed, the'driving gear is connecte'd directly to the churn shaft, and because of the eightupon'the churn shaft it.

I 'has been diflieutfto maintain the driving 'gearingjinisuch ali'nementas to obtain the fresults, and furthermore, the tmechanising ecomes inoperative in time, 'requii'ingreadjustment and rebuilding. Agg'great-l'nany hand operated chiirns have mai'rketed'iinwhe' past, and are, still in 'lrse, 'b1'it, sliiall inotors of theg'as and electric have induced; the adoptionbf power to negate churns, and knowing the desire -'of ft ose having hand'operated churns to uti- "3'0' lize ower, we have incidentally in view thei ea of supplying a readily connectible driving connectionto the old hand 0 erated churns," dering them capable 0 being power driven.

and a connecting arm that maybe readily appliedto the churh shaft, Said arm having a' crank connection with a driven" gear part.

Our invention further consists in the provision of a .drivingshaft t from the" shaft 'that drives the churn, and

" h a connected relation therewithi ot'to b afiected by the weight, th o I.

Fig. 6 is a view on the section line 0-0 of Fig. 2;

Fig. 7 is a detail view showing ordinary hand driven connection with churn shaft.

I Referring to the drawings, 2 are foot timber s spaced some distance apart. 3, 3 and Our invention relates to churns of the 3 are vertical standards and 4, 4 are cross framings, all of said parts being suitably connected to form a support for the work- I ing. parts of the machine. 5 are brace rods connecting vertical standards 3, 3 and 3 and the foot timbers 2 as shown. 6 is a barrel shaped churn body, the same being 0 provided with removable cover 7 (not described in detail as it constitutes no part of our invention).

8 is a (stub shaft"pro vided withcast late 9 which may be in'tpgral therewithfl? desired, said "shaft adapted to be supported in slot 10in the upper end ofstandard 3 and secured to the churn body. 1'1,for convenience ofreferencefwe shall designate as the revolubl member'" prises a drive shaft15 suitably su ported in I vertical standards 3* audit; aast pulley c 16 and. a loose pulley 17 on said shaft; 9; spur gear 18 secured-to the diaftandspaced from verticalstandard 3P'by'mea ns of collar hub- 19 of said ar the spur gear20 jourx naled upon stu shaft 21 and spaced from ivertical standard 3 Jby a hub ,22 of'said.

gear, saidgear being confined to said stub shaft in any suitable-manner; and thecranli connection between revoluble' meinber drive shaft 11- and gear 20,, comprising the eccentric pin 23 fixed to and spaced from the cen- I ter of gear- 20'and th'ejarm 2 fixedto revolu'blemember drive shaft 11, and itsouter 6 in '23. These, lflflifll' SPQOlfiB gear 20'and the slotted arm cdnnected with i the reveluhle member; drive shaft and their cooperation in connection with the other specified driving connections for the churn body, constitute the vital and essential feature of our invention, and produce the new result upon which our claim of invention is based.

It will be observed from the organization of parts exemplifiedby the disclosure that the mounting of the gears independent of the revoluble member drive shaft relieves said gears from liability of diversion from vertical alihement that might result from any sagging of revoluble member drive shaft 11. a A

What we claim is:

1. In combination, a'support, a mechanism thereon, means for driving said mechanism comprising a shaft connected with the mechanism, a crank arm on said shaft, a gear Wheel, a driving support therefor, said gear being provided with an eccentrically disposed pin connected with said crank arm, a power shaft, a gear thereon for driving said first named gear.

2. In a device of the class described, in combination, a support, an operating mechanism supported therein, a driving connection for saidfo'perating mechanism comprising a shaft journaled in said support and connected with said operating mechanism, a crank on said shaftsprovided with an open slot at its outer end, a suitably supported driving gear for said crank provided with an eccentrically disposed pin registering shaft and a gear thereon meshing with said first named gear.

4;. In a device of the class described, in combination, a support, an operating mechanism thereon, a shaft suitably journaled in said support and connectin the said operatiiig mechanism, means for riving said shaft comprising a crank arm onsaid shaft provided with an open slot at its outer end, a suitably supported gear wheel provided with an eccentrically disposed pin registering with the open slot in'said crank arm, a.

driving shaft and a gear thereon meshing with said first named gear.

In testimony whereof we aflix our signatures in presence of two witnesses.
